Corrugated Roofing Sheets and Metal Roofing Sheets Manufacturer for the Middle East

Corrugated roofing sheets are one of the most widely used building materials in the GCC, providing economical, durable and weather-resistant roofing for industrial, agricultural and residential buildings. Tianjin Sino East Steel Group manufactures galvanized corrugated sheets, color-coated roofing sheets and structural roofing profiles, supplying roofing contractors, distributors and project developers across the UAE, Saudi Arabia, Qatar and Kuwait.

What Are Corrugated Roofing Sheets?

Corrugated steel roofing sheets are formed from galvanized or pre-painted steel strip using a roll-forming process that creates a wavy profile. The corrugations add stiffness to the sheet, allowing it to span longer distances with less supporting structure. Roofing sheets are available in galvanized (GI), galvalume (GL) and pre-painted (PPGI/PPGL) versions, in profiles such as classic corrugation, trapezoidal and standing seam.

For the Gulf climate - intense sun, occasional sandstorms and coastal humidity - the correct substrate and coating are essential. Galvanized sheets offer good corrosion resistance at low cost; color-coated sheets add aesthetics and extended service life; structural profiles (0.8-1.5 mm) provide higher load capacity for industrial roofs.

Frequently Asked Questions

What is the difference between galvanized and color-coated roofing sheets?

Galvanized sheets have a zinc coating for corrosion protection; color-coated (PPGI) sheets have an additional paint system for aesthetics and extended service life. For visible roofs and coastal areas, color-coated sheets are recommended.

What profile is best for industrial roofing?

For industrial buildings we recommend trapezoidal profiles with a depth of 25-35 mm and base metal thickness of 0.4-0.6 mm, or structural profiles of 0.8-1.5 mm for long spans and heavy loads.

Can you supply roofing sheets cut to specific lengths?

Yes. We cut roofing sheets to your specified lengths from 1 m to 12 m, minimizing waste and installation time.

What colours are available for pre-painted roofing sheets?

Standard colours include red (RAL 3005), white (RAL 9002), blue (RAL 5010), green (RAL 6020) and brown (RAL 8017). Custom RAL colours are available on request.

Do you provide Mill Test Certificates with roofing sheets?

Yes. Each shipment includes an EN 10204 3.1 Mill Test Certificate covering substrate properties and coating weights.
